摘　　要：本研究采用水稻、小麦、玉米、大豆和番薯5种农作物秸秆,制成水浸提液与AM真菌结合施用,研究秸秆浸提液对AM真菌作用效果的影响,同时分析了5种秸秆浸提液的化学组分。结果表明,水稻、小麦、玉米和番薯秸秆浸提液显著提高了AM真菌对番茄根系的侵染,其中水稻秸秆浸提液处理的番茄生物量及地上部磷含量都有显著增加。经过GC-MS测定得到的各秸秆浸提液化学组分主要为酚酸类物质,这些物质可能对AM的调节发挥重要作用。In this study, five kinds of straw extracts（rice, wheat, corn, soybean and sweet potato） were used to investigate their effects on AM fungi inoculation and the components of these straw extracts were identified as well. The results showed that root colonization was significantly improved by adding rice, wheat, corn and sweet potato straw extracts. Dry weight and shoot P concentration were both significantly increased by rice straw extract. Main chemical components of each straw extracts identified by GC-MS analysis were phenolic acids, which may play an important role in regulating AM fungi.
